I successfully flashed back(yesterday)and then did the new update and rooted. Today I renamed the bloatware to .bak files. I also renamed the "backupassistant file to a .bak file. I just did a factory reset. My phone started up and I activated it. As I began to set up my accounts i.e google then the screen went black. I did a reboot and the phone will starup and show my wallpaper with the slide lock. As soon as I slide open the lock I get a black screen. I did a battery pull and again when I slie the lock open the screen goes black
